周原甲骨灼烧状况与风化原因研究

为了研究周原出土甲骨的灼烧状况与风化原因，用测色色差、X射线衍射、热重、扫描电镜和显微红外等多种分析手段对九种周原无字甲骨样进行了分析。结果表明，被分析样品都曾经受不同温度的灼烧，造成有机质丢失与骨头结构的破坏，这是导致甲骨风化的主要原因。出土后用酸浸泡清洗水垢，可能是导致甲骨风化的另一原因。在用于研究甲骨灼烧状况的诸多方法中，X射线衍射与扫描电镜分析两的作用突出。

Research on heating stages and degradation of oracle bones unearthed from Zhouyuan site

In order to investigate the heating stages and degradation of nine pieces of oracle bones unearthed from Zhouyuan, all of them were studied with X - ray diffraction, thermal methods of analysis, electron microscopy and micro - infrared spectrum . The results indicated that the analyzed oracle bones had been fired in different temperatures, it was one of the reasons of their degradation, after unearthed, they were rinsed by hydrochloric acid for removing scales, perhaps it was another reason of degradation. Among many methods for studying the heating stages of oracle bones, X- ray diffraction and scanning electronic microscopy play important roles.
